FEEDING- MECHANISM FOR RULING MACHINES AND THE LIKE.

Application filed April 8,

The present invention relates particularly to means for effecting and controlling the movement of sheets in ruling apparatus and the like.

6 One of the principal objects is to provide novel means of a simple and effective character, whereby two sheet moving means or devices can have different timed relations, while operating at predetermined speeds.

1 Another and important object is to provide novel means whereby one instrument, as

for example, the first feeder of a duplex machine, can be thrown out of operation, while the remaining mechanism continues, in order that the sheets already in the apparatus will pass through the same.

In the accompanying drawings 2-- Figure 1 is a diagrammatic plan view of the lay-out of an L ruling machine, showing the location and general arrangement of the novel mechanism.

The invention is disclosed in the form of an L ruling machine, in which sheets are first moved under ruling pens in one direction, and are then caused to move in a right angular direction beneath a second set of ruling pens to rule lines thereon at right angles to the first lines. The lay-out of such a machine is disclosed in Figure 1, wherein feeder is shown diagrammatically at 17. This delivers sheets to the first ruling machine 18, and from the ruling machine 18, the sheets are delivered to a turner or direction-changing device, indicated at 19. From this apparatus 19 they are fed to a second ruling machine 20. Inasmuch as the feeder 17 and ruling machines 18 and 20 may be of well-known character, it is believed to be unnecessary to show and describe them in detail, as their make-up is well-known to those skilled in the art.

The feeder 17 preferably employs a rotary suction feeding roller 21, such as that disclosed in my prior Patent, No. 1,494,303, dated May 13, 1924. An embodiment of the same is illustrated in Figures 15 and 16, wherein a driven shaft 22 has adjustably mounted thereon the roller 21. This roller is provided with rows of peripheral suction ports 23 in communication with bores 24 that in turn communicate with suction passageways 25, the bores and passageways opening through one end of the roller. The roller is journaled in a head 26, having a suction port 27, with which the inner ends of the passageways 25 successively aline. The port 27 is in communication with a suction pipe 28 leading to asuitable suction or exhaust pump 29, driven by any suitable means. In this pipe 28, and preferably at the sheet turning mechanism 19, is located a controlling valve casing 30. As shown in Figure 17, tlii valve casing contains a plunger valve 31, having a reduced portion 32 that is movable to a position to allow communication between the pump 29 and the suction roller 21, and is movable to a different position to cut off communication between the said pump 29 and roller 21 and open a vent 33 to the pump.

.The sheets, after passing the ruling machine 18, are carried by endless tapes 34 into the sheet turning mechanism 19, and are fed therefrom to the second ruling machine 20 by a suction roller 35. This suction roller is preferably of the same construction the suction roller 21 above described. The suc tion roller 35 has an exhaust conduit 36 leading to a valve casing: 37, and from said 'alve. using a conduit 38 leads to a suction or exhaust pump 39.

Extending across the path oi the sheets carried by the tapes 34. is a stop bar 40, and as shown in Figures ii} and l-l. secured by brackets it to this bar, is a suction pipe 42. having depcmling nozzles 43 with open lower ends, these norzlcs overlying lhe tapes l-l in advance ot the atop bar. The nozzles pre'le ably have forwardly evtendiiu; guide lingers at with upturned tree terminals if that direct the sheets carried by the tapes 5H: beneath the nozzles and against the stop har ell). Referring now to Figure t, the valve ltl5lll 1 3'? contains a plunger valve in having a reduced portion -15? that. i movable into and out of position to ati'ord conn munication between the suction conduit sections as and 38 and thus connect the teed rollerj'lo to the pump 30. The valve 46 also has a free end provided with a passageway 1118 that opem throne-h ite lower end. and has a lateral port 49 that is movable into communieation with the conduit 38 leading: to the pump 39 when the reduced portion el moves npvmrdly to cut ott communication between the conduit section 36 and 38. This lower end oi the valve is connected by a pipe 50 with the suction pipe 4-2.

Journaled on the rear end. of the machine is a main drive sl'iatti section 51. operated by any suitable means. and having lived there to between its ends a collar or head Another head 53 is lined to the inner end of the shalt section 51. Slidabl and rotatably mounted on the drive shaft section 51, between the heads 5:; and an. is a alcove fi l, one end of which may be knurled. ae shown at torming a handpiece. so that it may be readily moved. The other end of the sleeve rarries a cam 56, and this earn is provided with a pin 57. adapted to engage in any of a series of "sockets 5S lor1ne l. in the head. or collar 52. The cam is normally held locked to the collar by means of a coiled spring 43$) interposed between the knurled end of he sleeve F iaud the head as lifted to the shaft section at. Riding on the cam on, aa illustrated in Figure l. in the bearing; member (-30 oi a rocker arm 61. and this rocker a 111 has a link connection (:12 with the valve ll). Obviouely. therefore. upon each rotation of the driving; shaft section T l, the valve 31 is moved to opened. and then to closed position.

Alined with the inner end of the driving shalt section 51 is a driven. shaft section 63. *which as shown in Figure ll. has tixcd to it ahead 6% provided with a peripheral groove 65. The head 53 of the driving shalt section 51 has a longitudinally disposed driving pin (it; adapted to engage a driven pin ti'i' slidably mounted in the head (3-.1; and extending across the groove (55. Thin pin is norn'ially held in its projected position or in thepath ot' the pin on by a leaf spring lit). The pin (ST is provided with a notch (l9. one lace (it which is inclined. as shown at'lt) in Figure 12. it rock shall Tl. located alongside the shalt sections :31 and ti l (see Fig. 3) is provided with a cranl: arm 73 carrying a croes head '72 at its free end. and this head has a tapered -hoe 7*! adapted to enter the groove (59 oil the pin (3?. as shown in Figure 1:2. so as to he engaged by the inclined taco it) of the pin. (,iOllStttllt-Ellll) the rotation of the head will cause the pin to be withdrawn out ot the. path of the driving pin tilt. thus disconnecting the sha'tt 33 :lroin the shalt 51. The head Til. when in a position to have the shoe Tl engage the pin (37, is also in the path of pins projecting troni the periphcry of the head (ii. and these pins therciorc will abut against the head 73 and positively stop the rotati n oi the driven shatt f ection (33.

This driven -=hatt section carries a am To. on which rides the bearing element 77 ot' a rockc arm TH. and this arm has a link connection T!) with the valve 31 that con trols communication between the pump it and the "feeder suction roller The rocker arm To, as shown more particularly in Figure :3, also serves to opcra" a sheet counter. for example a register illustrated at St and the operating shall 81 thereof has a crank arin connection 82 with the rocker arm '78. The driven shai't section 8? turthermore is preteral'ily provided with an eccentric til} operating a pitn'ian hat. and this pitman actuatcs a swinging pawl 85 operating on a ratchet wheel 86. The ratchet wheel carries a sprocket wheel 87, having an endless sprocket chain 88, and this; sprocket chain is provided with one or more lugs 89 adapted to swing an arm 90. and 'lor example. operate a circuit closer Ell oi the alarm or other device. The operation ot' all these inetrnin ntalitics is obvionely controlled by the clutch actuation shoe Tlthat moves the driven pin (3T out oi engagement with the driving pin (ill or permits it. to have uch ei'i{. ;a renient.

The operation of the apparatus ie aa :tollowe. Aeeunning that all the parts are in operation. it will be evident that auction ii: periodically created in the suction. roller Lil, and thus in a manner readily ui'ideratooi'l. said suction roller will deliver sheets ten ceesively to the tirst ruling machine ltl. Paesing trom this ruling; machine. these sheets will be succesaively carried bythe tapes 3i against the stop bar ll), and inasmuch as suction is periodically created in till 1 iii liZtl the second roller 0-), the sheets at right angles from their first direction of movement and send them to the second ruling machine 20.

Inasmuch as the controlling valves for the first suction roller 21 and second suction roller are actuated by the common driving shaft 51, each of the cams that operatethe valves will be given one movement upon each rotation of the shaft. Their timed relations, however, can be altered. Thus, by sliding the sleeve 54, the pin 57 of the cam 56 can be disengaged from one of the sockets 58, and engaged in another socket. Thus the cam can be fixed in different positions about the shaft. On the other hand the cam 7 6, which operates the valve 31 controlling the first machine, will always be in one fixed position with respect to the driving shaft 51, since there is but one driving pin 66, and one driven pin 67. The two cams therefore, hough operating at the same speed, can have their relative positions altered, and the timing of the operation of the two suction rolls correspondingly altered. If, however, it is desired to stop the initial feed of the apparatus, itis only necessary to cause the crank arm 72 to swing downwardly, so that the shoe 74E will enter the annular groove 65, whereupon as the parts continue to operate, the pin, 69 will be withdrawn from the path of the pin 66, and the driven shaft 63 stopped. This obviously stops the operation of the valve 31, and the arrangement is such that the valve is stopped in its closed position, with the pump 29 out of commui'iication with the suction roller 21. The initial feed is consequently stopped, but the remainder of the apparatus continues in operation, so that the sheets already fed from the machine, continue on through. It will also be noted that when the driven shaft section 63 is stopped, the counting or registering mechanism is also stopped, so that there is no danger of the erroneous counting of sheets when the initial feed of sheets is stopped.

From the foregoing, itis thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, pro-portion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
